Comment(by veplaini):

 I have been testing with the scheduler priority code in the alsa
 module in Csound and it makes a good difference. However, I can only
 test it in the terminal, because from a sugar activity the set_scheduler
 function fails. I believe this is a permissions issue. I have set
 the /etc/security/limits.conf and this works for user olpc at
 the terminal, but activities are user '10002' and this does not
 work for them.

 Daniel, can you confirm the set_scheduler function is definitely
 working and setting the scheduler policy? I would expect it not
 to work for the same reasons as above. You can check its return
 value for errors.

 Any further suggestions?
